Image formation device using an I2C bus and a control method thereof

Abstract

An image formation device using an I2C bus and a control method therefor. The image formation device includes a plurality of detection sensors for detecting operation states of the peripheral devices; a plurality of A / D conversion units for converting into digital signals detection result signals output from the plurality of detection sensors; a plurality of slave devices for separating and storing by detection sensor the detection result signals converted into the digital signals by the A / D conversion units, and sending the stored detection result signals according to a signal requesting detection results; and a master device for requesting to the slave devices the detection result signal from at least one detection sensor out of the plurality of detection sensors in order to verify the operation states of the peripheral devices, such that the slave devices and the master device send and receive data to and from each other through a serial bus.

AI Technical Summary

Benefits of technology

[0019]An object of the present invention is to substantially solve at least the above problems and / or disadvantages and to provide at least the advantages described below. Accordingly, it is an object of the present invention to provide an image formation device with peripheral circuits simplified by connecting them with an I2C bus sharing and a control method thereof.

Problems solved by technology

However, there exists a problem in that the length of the harness becomes longer as the sensors or the switching elements are placed farther from the main controller 160, since the sensors or the switching elements are placed at fixed locations.

Further, various kinds of harnesses, and / or multiple or long wires of the harness may cause electromagnetic interference (EMI) or the electrostatic discharge (ESD).

Thus, the conventional image formation device has various problems which cause an increase in raw material costs, an increase in the number of assembly processes, both of which complicates the assembly process.
